WOOL-WASHING MACHINE.

SPECIFICATION forming part of Letters Patent No. 519,625, dated May 8, 1894.

Application filed July 31, 1893. Serial No. 481.965- (No model.)

To all whom it may concern.-

Be it known that we, WILLIAM BLACKBURN and ARTHUR WILLIAM BLACKBURN, both subjects of Her Majesty the Queen of Great Britain, residing at Oleckheaton, in the county of York, England,.have invented a certain new and useful Improvement in Wool-Washing Machines, of which the following is a specification.

Our invention relates to an improvement in wool washing machines of the class in which the wool is carried forward and washed by the action of a number of rising and falling troughs or posses having perforated bottoms which dip into the liquid in the tank in their falling motion and in their rising motion allow such liquid to pour back upon the fleece in finely divided streams such streams not only cleansing the fleece but forcing the same forward from the entering to the delivery end of the tank. Such an apparatus is fully described in the United States patent to W. Eastwood and AVAmbler, No. 460,852, dated October 6, 1891.

The accompanying drawing represents a side elevation partly in section of the machine covered by the patent above mentioned having our improvements applied thereto.

The apparatus in question will be readily understood by reference to the foregoing patent and it will not be necessary to again explain the action of said apparatus further than to say that the fleece is fed into the tank 1 by the endless apron 8 and passes out between the delivery rollers-12, 12 onto the apron 13 the movement of the fleece through the sud or water in the tank being obtained by the rising and falling motion of the troughs or posses 2 which are lifted by means of the eccentrics 4'connected to the troughs by means of the chains 3 which in turn pass over the pulleys 3 on a counter shaft 3 The troughs are provided with perforated bottoms through which they fill as they descend into the tank and which permit streams of liquor to fall upon the fleece as they rise. A perforated plate 11 is provided at the delivery end of the tank through which the suds pass onto the perforated plate 15 into the tanks 15, 17 and 19 in which thesolid matter is precipitated and from which in the apparatus in question the suds were raised by means of the pump 9 and pipe 10 to the per forated supply tank 20 from, whence it fell I into the tank 1.

According to our present invention we cause the pipe 10 to deliver in addition into a main 10 arranged above the troughs 2 such main being supplied with branch pipes l0 provided with regulating taps 10, the branch pipes dipping into the troughs 2 and supplying same with the sudsdirect the object being to provide the troughs with a better supply of the suds than they can pick up by simply being lowered into the tank and raised The grate conthe latter is kept in an open and fleecy condition so that dirt and sand can be readily removed by the action of the sud and troughs. The additional grate 1 is useful for the purpose of clearing out most of the dirt and sediment before the wool arrives at the grate 11 through which the remainder will escape. Beneath the perforated grate 1 is a box 1 which catches the sud and sediment and allows it to pass through an opening in same to the perforated plate 15 What we claim isv r In a wool-washing machine, the combina tion with a tank, a series of rising and fall- 0 ing troughs, and a grate -11 situated at the delivery end of the tank, of a supplemental grate 1 located beneath one of the troughs, and a box 1 beneath same having a discharge opening, the supplemental grate beour hands in the presence of two subscribing ing adapted to remove a large part of the dirt witnesses.
